I'm working on a '71, 9.8. Naturally the impeller was bad so I thought I'd just replace the whole pump. The replacement arrived and the bottom housing seal is installed upside down, that is to say the lip is pointing OUT. I know the TOP seal is installed this way but on my original pump, the bottom seal is installed with the lip IN toward the water side of the pump. The parts manual APPEARS to show the seal installed as the original was... lip up toward the impeller.
Can anyone confirm which way the seal is supposed to go? Was there a production change that turned the seal over for some reason? It would SEEM that the lip should go toward the water side to prevent the water (at higher pressure than the gearbox) from making it into the gearbox.
Thanks for any help,
Steve
